Answer:
The correct answer will be- zygote →cleavage→ morula→ blastula→ gastrula.
Explanation:
Human embryogenesis is the study of the formation of an embryo from the zygote formed after the fertilization of the sperm and egg cell.
The fertilization takes place in the ovarian duct in females which form a diploid zygote. The zygote starts the process of cleavage that is cell division and differentiation and leads to the formation of a 2 celled stage, 4 celled stages and later 16 celled stage. The 16 celled stage is known as morula which further undergoes cleavage and form blastula. The blastula now forms a gastrula with 3 layered distinction- the ectoderm, endoderm and mesoderm through gastrulation.
Thus, zygote →cleavage→ morula→ blastula→ gastrula is the correct answer.
Answer:
B. ATP & NADPH
Explanation:
fruits and vegetables are full of energy. Energy in the form of glucose. The energy from sunlight is briefly held in NADPH and ATP, which is needed to drive the formation of sugars such as glucose.
As Melvin Calvin discovered, carbon fixation is the first step of a cycle. The Calvin cycle transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transport chain, excited electrons lose energy to NADPH and ATP. In the Calvin cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose.
Answer: the male duct system is a series of ducts the sperm passes through during ejaculation. these are the components of the male duct system epididymis, ductus deferens, ejaculatory duct, and urethra.
Explanation: Below is a diagram of the male duct system
